Please answer each section as they are parts of a whole problem. This must be C++ code

2. Write C++ code using vec.h to accomplish cach of these tasks. You may assume that u, V, and w are of type vec3 and that a and b are scalars of type double. (a) u = u = (2,3,5) u (b) w 3 +-V 6 1 (c) w = 3ux v (d) Normalize u in place. (e) w = (4+1)v. + (f) a=u. V Juv (g) a = 10 (get the first entry from the vector)
